Description

Give your emerging rider the best start in their BMX racing career by getting a Chase Race Series Pro under them. If your rider is just getting their first serious race bike, then this mini is the perfect sized race bike for them.

Chase know a thing or two about winning and this experience flows all the way down to their smaller bikes, and entry level bikes like the Race Series. With an all aluminium frame and chromoly forks, it's built from the same race winning materials as the Edge bike range and means that it'll handle anything your young racer can throw it at.

Add in double-walled alloy rims and this Chase Expert will take on biggest, baddest tracks with ease and when your rider is ready to move up to the next sized bike, the build quality and reputation that the Chase name brings ensures that this race rig will be ready to pass down to the next rider coming up in the family, or passed onto another young shredder.

Available in two contrasting colour schemes, the skittles version will suit the extrovert, while the quiet achiever will pick the black/grey Chase to let their riding do the talking out on track. Either way, this bike is one of the best entry level race rigs available.

Assembly information

Your bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

Fit the handlebars and line them up with the front wheel
Fit the front wheel, pedals and seat post
Check the brakes and tyre pressure before the first ride

Tools: Allen key set and a 15mm, 17mm or 19mm spanner for the pedals and axle nuts (bikes can vary between these three sizes). A socket is needed if installing pegs.
